Hello all,I'm ashamed of

Hello all,

I'm ashamed of myself for not knowing this was a thing all this time. I'm trying to make up for that by spreading the word to any friends who are willing to join in as well.

Very excited to be contributing my iMac's modest 3.4GHz i7 CPU and AMD/ATI GPU to the project.

I've been doing a little googling here and there, and I was wondering if anyone might have any insight into the current issue I'm running into.

I'm running a task called "Gamma-ray pulsar search #5 1.08 (FGRPSSE)" and it appears to be stuck at 69.344% where before I walked away from my computer, had at the very least reached 70%.

I restarted my computer, restarted BOINC, and there still seems to be no progress being made, however, it does say that the task is "running". Since the restart I've left it alone to do it's thing in hopes the progress bar will update on its own in a few hours.

If need be, I will gladly paste the required lines from the Event log.

Hope everyone is safe and healthy! Thank you in advance for any assistance or advice.

UPDATE: some progress has been made! I guess I just had to leave it alone. Sorry everyone.

Click on the "stuck" task in

Click on the "stuck" task in the Manager and in the left hand panel, select Properties.

Look at the time the task last checkpointed to see if it is recent and within the normal period you have set for checkpoint time.

Look at the progress rate and make sure it is not 0%.

Cpu tasks should normally show  the %complete and time remaining but that depends on the project and whether the app designers programmed that into the app.

Boinc has its own method of providing a "quasi" or "fake" %complete and remaining in the Manager for those apps that do not provide the actual values.  It can get those very wrong sometimes.

Hi MCarbone90,  welcome to Einstein@Home.  Thank you very much for deciding to join.

I don't know that you really have a problem.  Your 69.344% looks suspiciously close (if the '6' was perhaps an '8') to a value where there is always a lengthy pause just before 90% completed.  At that point, the primary calculations are complete and a series of 'followup' calculations (the last 10%) are performed to create a 'top ten' list of the most likely candidate signals.  That can take quite a while, and when finished, the progress jumps straight from ~90% to 100% and the full results are returned.

You have posted into the Technical News forum where the Project Staff make announcements about new or updated apps and where volunteers give feedback about bugs, etc., with those new apps.  This thread is very old and the app seems to be operating in a long term stable manner so the behaviour you see is probably normal for the app and perhaps there might be a sub-optimal configuration with your computer.  Particularly for someone just starting, the best place to get help with that is by starting a new thread, probably on the 'Problems' board if you think there is a genuine issue. 

Your computers are 'hidden', which is the default setting.  To get the best help, you need to give, either complete hardware/software details, or allow other volunteers to see those details by changing the setting on this page.  This only allows non-private information to be seen and is not a threat to your security.  If you want to allow your stats to be exported to statistics sites, you'll need to change that setting as well.  There is no security issue with that if you're willing to share.  If you make changes to settings, don't forget to find and click the 'Save' button.

If you have any further issues or queries, please don't hesitate to post a new thread in the "Help Desk" section.

Cheers,
Gary.

Gary and Keith! Thank you so

Gary and Keith! Thank you so much for your answers. You've both been extremely helpful. You both were absolutely right! Certainly not a major issue as it seems to have worked itself out. Please excuse my lack of experience with BOINC related anything. I will direct any future questions to more appropriate message boards.

I am getting a lot of error

I am getting a lot of error on these tasks and this is an example  https://einsteinathome.org/task/947581934

On this particular machine I have 15 errors and 16 Valid.

you're looking at the wrong tasks. that is a task that looks like you manually aborted. you have 4 such Aborted Gamma Ray tasks for that computer. These are from early May.

 

All of your recent errors are from Gravitational Wave tasks. These failures usually happen when you run out of GPU memory. Your GTX 1660ti with 6GB of memory is enough to run these tasks at 1 WU at a time, but perhaps you are running 2-3 WUs at a time? if so you should reduce it to just 1 at a time.

GW tasks can require 1-3.2GB EACH. and your GPU will have several hundred MB GPU ram unavailable since it's tied up running the Windows desktop. so 2x 3GB tasks, or 3x 2GB tasks will exhaust your memory and produce errors like this.

Thanks I was running two

Thanks I was running two tasks on the GPU so I changed back to one and it is running fine now.

Any estimated time to return

Any estimated time to return of Gamma-Ray task generation?
